The spatial mean and standard deviation of these data were included as possible variables, as well as the area and perimeter ratio of the polygons. [...] Very limited alteration of the wetland boundaries or changing of the wetland class was done in the QC process. [...] Unlike the rest of Alberta, Sentinel-1 SAR data was not used in this classification because of issues of radar layover, foreshortening, and shadowing in mountainous areas, and because its inclusion did not improve the accuracy of the final product. [...] The next version of the ABMI Wetland Inventory aims to add in the classification of seasonal and temporary wetlands in the Boreal transition zone to better reflect seasonal wetlands across all of Alberta.
